I am trying to extract wanted text from a given set of text. I have created below function.

   def extract_name(title):
        matches = re.findall(r'\b[A-Z0-9\s&.,()-]+(?:\s*\(\d\))?\b', title)
        return ', '.join(matches) if matches else None

But, it produces unwanted (, , for some titles. For example, my title are like below.

THETA COMMERCIALS (2005) LIMITED, TEST CONNECTIONS LTD (In Relation), NANO CARE LIMITED (In Relation)

Expected outcome: THETA COMMERCIALS (2005) LIMITED, TEST CONNECTIONS LTD, NANO CARE LIMITED
